She’s asking women nationwide to show a little skin today, hoping to prove to the sheik that a little shake never killed anyone. What started as an Internet joke has morphed into social media mayhem with more than 50,000 women expected to join the “movement” through McCreight’s website blaghag.com.

Boobquake isn’t about running around topless — but rather, showing a little more skin than you normally do. For McCreight, she’s trading her usual T-shirt for a more skin-baring tank top.

“It’s a personal statement for anyone who wants to take part in what they consider ‘immodest,’” she told The Post last week. “To some people, showing ankle might be ‘immodest,’ and that’d be fine.”

To celebrate “boobquake” day, we enlisted plus-sized stunner Lizzie Miller, whose generous curves have appeared in Glamour magazine (naked, twice!), Italian runways and catalogs like Lane Bryant, to model some of this season’s fab full-figured fashions.

Persian religious boob Sedighi can expect a seismic shakeup when he gets a load of this zaftig beauty showing off her assets.

“OMG! I wonder if he saw my Glamour photos? I’m sure they caused a volcano to erupt . . . in Iceland, because of me,” she laughs. “I think it’s really important for women to accept their bodies. If you want to show a little leg, show a little leg. Most of the time, women do it in a tasteful way.”

If you’re planning to use your underwire to undermine the imam’s geology, remember this: More is more, but too much is less sexy. Pick a body part — gorgeous gams, bootylicious behind, treasure chest — and highlight it, just not all at once. And don’t forget, it’s all about attitude.

“It’s all about confidence. Confidence is sexy,” says Miller. “American women are confident. Showing your cleavage is not going to cause an earthquake!” Sure, you might not trigger a natural disaster — but give them enough of an eyeful, and you could cause a three-car pile-up on Broadway.
